Professional Applications & Engineering Value
These 3/8"-16 UNC brass flat head screws deliver critical performance in applications where corrosion resistance and thread precision are paramount. The coarse UNC thread design provides excellent engagement in softer materials and prevents cross-threading during assembly. With fully threaded construction and Class 3A thread fit, these fasteners maintain consistent clamping force in vibrating environments. The 82° countersink angle ensures flush mounting in precision-machined components, while the hex drive configuration allows for high-torque installation without cam-out. Ideal for electrical enclosures, marine hardware, plumbing systems, and industrial equipment where brass fasteners prevent galvanic corrosion and maintain long-term reliability.
Specification Summary & Compliance
This flat head screw features precision UNC coarse threads with Class 3A fit for tight tolerance applications. Manufacturing conforms to ASME B18.3 specifications, ensuring dimensional accuracy and performance consistency. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, containing no restricted substances. Thread diameter maintains exact 0.375" specification with proper 16 TPI spacing throughout the 1 1/2" length.
